Nigeria: Dangote Cement says that it co-processed 89,000t of waste as alternative fuel (AF) in its cement production as a group in 2021. The Nigerian Guardian newspaper has reported that the source materials consisted of biomass, waste tyres, fly ash and oil-based waste.

Speaking on International Mother Earth Day on 22 April 2022, head of AF projects Peter Anagbe said that the company continues to demonstrate its commitment to sustainable waste management through its advancement of local community recycling projects.

US: Cemex USA plans to increase its rate of alternative fuel (AF) substitution at its 2.2Mt/yr Brooksville, Florida, cement plant to 30%. It will also increase its AF use at its 1Mt/yr Demopolis, Alabama, cement plant. At both plants, the new fuel mix will include biomass. The producer says that it will complete the plants’ transitions before 2023.

Philippines: Holcim Philippines says that its waste management partner Geocycle processed 200,000t of biomass and industrial and municipal waste into alternative fuels (AF) and raw materials for use in its cement production in 2021.Global Cement previously reported that Holcim Philippines co-processed 100,000t of AF in 2020. The company is targeting 70% AF substitution in all of its cement production.

Canada: St Mary’s Cement plans to apply for a licence to substitute alternative fuel (AF) for a part of its coal, gas and petcoke fuel mix. The plant previously held a two-week AF substitution trial in May 2011. CBC News has reported that the subsidiary of Votorantim Cimentos will present its plan at an evening meeting for the general public on 18 November 2021. The company says that it plans to implement similar AF arrangements to those at its Bowmanville plant, where it uses 90,000t/yr of biomass, wood from construction and demolition and non-recyclable paper and plastics.

Environmental manager Ruben Plaza said "Lower CO2 emissions is the first consideration and, equally as important, the material has to be approved and available in sufficient quantities with a reliable and sustainable long-term supply."

India: Dalmia Cement has sought to acquire 2Mha of land from the government for use in bamboo production. The company plans to use the bamboo to produce bio-based alternative fuel (AF) for its cement production. BusinessLine News has reported that the company plans to obtain brownfield sites in order to restore them to grow the crop on.

Norway: Norcem plans to invest up to Euro8m on upgrades at its integrated Kjøpsvik cement plant to improve its receiving, handling and feeding of alternative fuels. The project will be implemented by 2023. The work will include installing new storage and dosing systems for waste oil, FAB pellets and bone meal.

India: JK Cement has signed a strategic memorandum of understanding (MoU) with Punjab Renewable Energy Systems (PRESPL). Under the agreement, PRESPL will supply its technologies and forward-integrated value chain for use by JK Cement in scaling up alternative fuel (AF) substitution at its cement plants. The transition will focus on biomass-based fuel use.

Managing director Raghavpat Singhania said "As we embark on our journey towards decarbonisation, we commit to this MoU that allows us and PRESPL to build deeper synergies in the bio-energy sector.” He added that the agreement promised ‘a better future with a win-win for the environment, people and energy in India.’

Russia: Holcim Russia has committed to realising a 15% CO2 emissions reduction in its cement production between 2019 and 2030 to 475kg/t from 561kg/t. It plans to further reduce its cement’s CO2 emissions to 453kg/t by 2050, and to implement further measures to ensure its net carbon neutrality at that time.

Corporate relations director Vitaly Bogachenko said “The company's goal is to drastically reduce carbon emissions, and there are two working solutions for this. The first is the use of alternative fuels (AF) obtained from different types of waste: residues of municipal solid waste after sorting and extraction of all useful fractions from them, used tyres and others. The presence of biomass in them makes such fuels carbon neutral, so emissions during production are significantly reduced. The second solution is to replace carbon-intensive raw materials. For example, instead of limestone, we use slags. The 'recipe' for cement is completely different: thanks to the new composition and the lower temperature during the firing process, the carbon footprint in the production of cement is reduced.”

Japan: Taiheiyo Cement has installed three BWZ bucket elevators and a Louise TKF drag chain conveyor supplied by the Hong Kong-based subsidiary of Aumund at its new power plant at Ofunato. The cement producer uses both biomass and coal at the plant.

Two elevators and the drag chain conveyor are used to transport palm kernel shells (PKS) and palm empty fruit bunches (EFB), which are used as alternative fuels in the power plant. Each has a capacity of up to 150t/hr. The conveying concept is designed so that the different materials are kept apart and enter the silo buffer tanks separately. The third bucket elevator is used for coal handling. It is a gravity discharge type BWZ-S elevator with a capacity of up to 35t/hr.

Spain: Cementos Portland Valderrivas has announced plans to reduce the greenhouse gas emissions of its 1.6Mt/yr integrated Alcalá de Guadaíra cement plant in Andalusia by 40% through the substitution of biomass for coal in its kiln lines. The company said that it regretted the confusion caused by “manipulation of information” around the plans in a local environmental group’s communiqué. It said, “the plant has all the permits and the cement group is looking forward to this new challenge.
